2 men go fishing, One has a stutter.
The man with a stutter says “shh ssshhh sshh”. The other man says “what is it, did you catch a fish”? The stuttering man continues to make ssshhh noises, the other man says “spit it out”. The stuttering man says “ssshhh ship!!” Before the 2nd man can react a ship crashes into their boat.
Months later they both have recovered and go on another fishing trip.
The stuttering man again starts saying “ssshhh”.
The 2nd man starts panicking thinking he’s going to get hurt again.
The 2nd man jumps out of the boat as fast as he can, the stuttering man says “sshhh sshhh Shark!!”
